What type or driver will you be working on? What does the driver do? Based on answer to those the correct / recommended access/interface method varies. Note the driver and kernel extension model between Linux and Mac OS X is different and so talking about direct parallel is likely not the best way to attack things, instead outline what you need or are trying to do / implement.
